Research roundup: Patients hesitant to focus on costs; Increase in primary care demand is uneven

One way to contain health care spending is to get patients involved in weighing costs of treatment options with their doctors. Researchers recruited 211 medically insured participants to assess their willingness to consider costs when choosing treatments.
